Salad of boiled vegetables and beans

We take any beans, but I like the red one more, put it on at night, let it swell, then cook. We also need to boil vegetables in a uniform. These are potatoes, beets and carrots. After they are ready, remove the skin and cut into small squares. Naturally, the amount of ingredients that I indicated is all approximate. For example, I like it when there are more beets and carrots in the vinaigrette, then it turns out sweet, and others like to throw potatoes more. Next, we need to cut the onion and pickled cucumber, and pickled, but that it would be sour. I add it at the very end and to taste. Now mix the vegetables with sauerkraut, beans and pour sunflower oil. I want to give one more little piece of advice. If you are preparing this salad for guests, then do not add onions, because if it stands a little, the vinaigrette becomes a little bitter. And if it's just for your household for dinner, and you know that they will eat it in the evening, then of course cut it, because onions are very useful.
